Kant holds that some nonhuman animals “are acquainted with” objects, despite lacking conceptual capacities (“understanding”). What does this tell us about his theory of human cognition? Numerous authors have argued that this is a significant point in favour of Nonconceptualism—the claim that, for Kant, sensible representations of objects do not depend on the understanding. Against this, I argue that Kant’s views about animal minds can readily be accommodated by a certain kind of Conceptualism. It remains viable to think that, for Kant, (i) humans’ sensible representations necessarily represent objects as temporally structured in ways that allow us to have thoughts about them, and (ii) such representations are produced, and could only be produced, by the understanding. This allows Conceptualists to maintain that humans’ sensible representations depend on the understanding, while accepting that animals have sensible representations of objects too. We must, therefore, reassess both the warrant for Nonconceptualism and the shape Conceptualist readings must take.

This article advances a new account of Kant’s views on conceptualism. On the one hand, I argue that Kant was a nonconceptualist. On the other hand, my approach accommodates many motivations underlying the conceptualist reading of his work: for example, it is fully compatible with the success of the Transcendental Deduction. I motivate my view by providing a new analysis of both Kant’s theory of perception and of the role of categorical synthesis: I look in particular at the categories of quantity. Locating my interpretation in relation to recent research by Allais, Ginsborg, Tolley and others, I argue that it offers an attractive compromise on this important theoretical and exegetical issue.

I give an argument against nonconceptualist readings of Kant’s First Critique, according to which one can enjoy a Kantian intuition without possessing any concepts, and present an alternative reading. The argument is that nonconceptualist readings are forced to construe the Transcendental Deduction in one of three ways, none of which is acceptable: The Deduction is seen either (i) as inconsistent with the Transcendental Aesthetic; or (ii) as addressing a question of fact rather than a question of legitimacy; or (iii) as articulating a position that Kant himself criticizes as a form of scepticism. Consideration of the third alternative, in particular, shows that a more promising construal of the Deduction must be based on a different interpretation of Kant’s claim that intuitions and concepts constitute two distinct kinds of representation than is assumed by proponents of nonconceptualist readings. I present such an interpretation and outline the alternative reading of the Deduction that results.
